“Wow! The last 24 hrs have been the best of my life. Forever changed, I am now a father. Maxfield David Ladin,” the proud papa announced via Instagram, showing off a picture of his son born on Friday (December 21).

The Killing star and his fashion designer/stylist wife announced their pregnancy news in May. “Eric and Katy are expecting and couldn’t be happier,” his rep told Celebrity Baby Scoop.

Eric burst into the acting world with his breakout role in HBO’s Generation Kill. He is also known for his recurring role as January Jones’ brother in Mad Men, as well as his recurring role as Chloe Sevigny’s diabolical doctor/brother in HBO’s Big Love.
